Question

In the given figure, find x and y.
65°​

Answer 1

Step-by-step explanation:

Y = 65*2 = 130 Degrees

X = 25 degrees

Answer 2

Answer:

y = 65*2 = 140° [ angle at the centre is twice the angle made by an arc at any other point on the circle ]

|OAB = |OBA = x [ OA = OB radii , angle opposite to equal sides are equal ]...........(1)

in ∆ OAB, |OAB + |OBA + |AOB = 180°

=> x + x + 130° = 180°

=> 2x = 180° - 130° = 50°

=> x = 50/2 = 25°

therefore y = 130° and x = 25°
